Umshini we-junda sandblasting kanye nomshini wokudubula we-junda udubule uyimishini emibili ehlukile. Yize igama liyafana, kunomehluko omkhulu osetshenziswayo. Kodwa-ke, ukuze ugweme iphutha lokukhetha umsebenzisi, kuthinta ukusetshenziswa futhi kubangele imfucuza yezindleko, umehluko ohambelana nokwethulwa ngokulandelayo.
1, umehluko phakathi kokuqhuma kwehlumela kanye ne-sandbsting
Isisekelo sokudutshulwa kwe-peening ne-sandbsting yindlela yokuhlanza ingaphezulu lomkhiqizo usebenzisa umoya njengamandla. I-Shot Peening isebenzisa i-metal abrasive, njengokudutshulwa kwensimbi, isihlabathi sensimbi, ukudubula ubumba. Ukuqhuma kwesihlabathi kusetshenziswa yi-abrasives engeyona eye-metallic, efana nesihlabathi seCorrundum, isihlabathi sengilazi, isihlabathi se-resin nokunye.
2, uJunda wadubula ukuqhuma nenqubo yeSandblasting
Inqubo yokudubula ye-Shot kanye neSandblasting isuselwe kwimikhiqizo ehlukene, ukusebenza kanye nezinye izidingo zokuthola ukuthi uyisebenzisa yini i-Shot Peening noma iSandbsting.
3. Ukukhetha ukuqhuma kwe-Shot kanye nemishini yokuqhuma kwesihlabathi
Shot Peening and Sandbsting ngaphezu kokuvuselelwa okuhlangene, okulimazayo, idivaysi yokuhlunga ehlukumezayo yehlukile, eminye amadivaysi emishini ayafana, vele, izinhlayiya ezincane ezihlukunyezwayo nazo zingaba yimishini yangempela.
4. I-Shot Peening yindlela yokususa ukugqwala kwensimbi ngokusebenzisa umoya ocindezelwe noma ama-mechanical centrifugal Force njengamandla nokuxabana. Ububanzi be-projectile buphakathi kuka-0.2-2.5mm, umfutho womoya ocindezelwe ngu-0.2-0.6MPA, kanye ne-angle phakathi kwe-jet nobubanzi kungama-30-90 degrees acishe abe ngama-30-90 degrees. Ama-nozzles enziwe nge-T7 noma i-T8 yethuluzi lensimbi futhi aqine kanzima nobulukhuni obungu-50-. Impilo yenkonzo ye-nozzle ngayinye iyizinsuku eziyi-15-20. I-Shot Peening isetshenziselwa ukususa isikali, ukugqwala, isihlabathi sokubumba kanye nefilimu endala yokupenda kusuka emikhiqizweni yensimbi ephakathi nendawo naphakathi nobukhulu obungabi ngaphansi kwe-2mm noma ukusakaza kanye nokukhokhisa izingxenye ezingadingi usayizi oqondile kanye ne-contour. Kuyindlela yokuhlanza ngaphambi kokuhlanganiswa komhlaba (Plating). Kusetshenziswa kabanzi emagcekeni amakhulu emikhumbi, amafektri asindayo wemishini, amafektri ezimoto nokunye. Ukwelashwa okungaphezulu nge-Shot Peening, amandla aqhamukayo, umphumela wokuhlanza asobala. Kepha udubule ukucubungula kokusebenza kwepuleti okuncane, okulula ukwenza i-workpiede deformation, futhi ukudutshulwa kwensimbi kushaye indawo yokusebenza noma ukudutshulwa, ukuhlukunyezwa kwefilimu, ukuhlukunyezwa kwefilimu, ukuqhuma kwefilimu, ukushaya i-pening akukwazi ukususa ngokuphelele uwoyela.
I-5, iSandblasting nayo iyindlela yokuhlanza yokuhlanza, kepha iSandblasting ayidutshuli ukuqhuma, iSandbsting isihlabathi njengesihlabathi se-quartz, ukuqhuma kwe-shot kuyinto pellet yensimbi. Ezindleleni ezikhona zokwelashwa komhlaba, umphumela wokuhlanza wokuhlanza isihlabathi. I-sandblasting ilungele ukuhlanza indawo yokusebenza ngezidingo eziphakeme. Kodwa-ke, imishini yokuqhuma yesihlabathi yamanje yaseChina yahlanganiswa kakhulu i-hinge, isikhali, i-lifti enyukeji kanye neminye imishini yasendulo yokuhamba ngesihlabathi esindayo. Abasebenzisi badinga ukwakha umgodi ojulile futhi bafake ungqimba olungenamanzi ukufaka imishini, izindleko zokwakha ziphakeme, ukugcinwa kwezindleko zokugcina zikhulu. Ngokunakwa kuzwelonke ekuvikelweni kwemvelo kanye nempilo yezimboni, ngoba inqubo enkulu ye-sandblasting inenombolo enkulu yothuli hhayi ukungcoliswa okukhulu kwemvelo, kepha futhi kulula ukuholela esifweni somsebenzi we-opharetha (i-silicosis), inenombolo enkulu yokuqhuma iqhuma ukuze ungene esikhundleni se-sandblasting.
Okungenhla kumayelana nomehluko phakathi komshini wokuqhuma kwesihlabathi kanye nomshini wokudubula, ngokwesingeniso sayo, singaqonda kahle ubukhulu besicelo futhi sisebenzise izici zalo zokusebenzisa, ukuze sikwazi ukufeza izidingo zayo.
